Anyone who has heard the snap of a rubber band breaking knows it's time to reach for a replacement.
But a group of French scientists have made a self-healing rubber band material that can reclaim its stretchy usefulness by simply pressing the broken edges back together for a few minutes.
Shape-memory materials spontaneously change shape when exposed to an external stimulus, such as heat. Materials chemists have now made a shape-memory polymer that reversibly changes colour as it changes shape, enabling repeated transitions to be easily monitored even when the shape change is small.
The leading specialty chemicals group, Evonik, introduces new generation of silicas as reinforcing fillers in silicone rubber applications.
AEROSIL fumed silicas from Evonik serve as reinforcing fillers in silicone rubber applications improving mechanical properties such as tensile strength, tear resistance and, almost incidentally, ensures that the rubber has good transparency.
Hollow objects with demanding requirements like hairspray bottles, paint cans or oil tanks can now be made of polyoxymethylene by means of extrusion blow molding.
In comparison to containers made of polyethylene (PE), Ultraform E3120 BM, now available in commercial quantities, displays considerable better barrier properties against gases and are resistant to many types of media such as alcohol or oil.
ALUMINIUM 2008, World Trade Fair and Conference 23 - 25 September 2008, Messe Essen - Every two years, the aluminium industry presents the European Aluminium Award to honour the best new developments in the industry. At this year's ALUMINIUM 2008, the award will be presented for the sixth time already.
The HMS Fearless, a British Navy warship launched in 1963 and withdrawn from service in 2002, is to be recycled in Belgium. The ship weighs 11, 060 tonnes. From this, almost 7, 000 tonnes of waste and scrap, including steel, will be extracted and sorted.
BALI, Indonesia, Dec. 11, 2007 - In the quest for more environmentally friendly automobiles, global steel companies have aims to reinvent the steel automobile body.
As the consensus builds for comprehensive reductions in greenhouse gas (GHG) emissions across international boundaries and industries, global steel companies are reinventing the deployment of steel to reduce GHG emissions, while still providing safe and affordable personal transportation for an increasing mobile global society.
Antifouling coating treatment, developed by an innovative provider of fouling defense solutions, is used with aguaculture nets made with durable Dyneema fibers.
The Netherlands Society for Nature and Environment and the three technical universities of Delft, Eindhoven and Twente are launching their stimulating vision on mobility. At the pavilion 'Car in the Future' they will present the mobility concept c, mm, n.
